A person can make a decision intuitively, not based on experience. Or take into account your personal preferences at a given time. And they can depend not only on logic, but also on the weather, health, surroundings, etc.
And the machine has a well-proven algorithm.
The brain is the same "Chinese room" as the operating system of the machine (who is interested in the "Chinese room", and in general all Turing's ideas on this subject, google).
The brain makes decisions in a split second (and sometimes in a few seconds, according to the latest neurophysiological studies) before you realize this decision. And all our subsequent so-called thinking is just adjusting the justification to the already made decision)
There is one more aspect, descriptive. It is possible to understand exactly how a person "makes a decision" only from the description of the person himself. And he is able to describe not the process itself, but his idea of the process. That, as you understand, are different things)
So we only have access to data at the input and data at the output - in the case of a machine, in the case of a person. And what happens inside the "black box" is a random process that is inaccessible to us) In the case of the car, this is precisely the perspective of the Doomsday, described by Cameron in "Terminator 2".
The machine is guided exclusively by logic. Sometimes simple, linear, sometimes it uses sophisticated methods based on complex algorithms and analysis of huge amounts of data. But this is still only logic.
The emotional and moral sphere plays a huge role in human behavior. This is so, even if the person himself does not realize this and does not admit it.
Perhaps someday machines will become so perfect that they will acquire emotions and the ability to be guided by the principles of their own morals. It is very likely that their emotions and their morals will be very different from ours. But this is still a long way off.
Almost nothing. Because the process of making a decision by a machine is actually a process of making a decision by a person, embedded in an algorithm and implemented in software. The only difference is that the machine cannot be distracted, replace information with hopes, arithmetically make mistakes, well, etc. But this difference is not such a difference, since sensible citizens are also not distracted and also do not take wishful thinking.
The complexity of the algorithm for choosing a solution to the problem.
Approaching this choice.
Different machines make decisions using different algorithms, which may involve different patterns of behavior, but the process will always be the same.
Obtaining a problem -> choosing a behavior pattern -> calculating possible options -> choosing decisions.
And this very calculation is carried out only on the basis of the results of certain mathematical calculations.
A person also has a similar algorithm (of course, people have it much more complicated), but we “estimate »The best option, based on our experience, advice from our closest environment, mood, you name it.
It is for this reason that machines, WHETHER, cannot make balanced and adequate decisions in everyday life, but in specific areas of life, such as chess, people will never be able to get around the car.
